Application filed January as,

In automatically lubricating of the type having an oil reservoir in the bottom thereof from which the oil is conveyed by suitable means to the parts to be lubricated, such as the bearing and journal within the box, trouble is experienced by reason of the escape of oil through the openings in the walls of the box and particularly through the opening hrough which the shaft extends, which opening is usually closed against the entrance of lneans ot a dust guard. Such trouble usually results from the fact that the boxes are provided with too much oil, bringing it above its. normal level and thereby causing the distribution oi a surplus quantity of the oil with a consequent loss of same. Furthermore, it has been found that the over supply of oil in the box is sometimes so great as to bring it into contact with the dust guard,

with the result that the latter, which is usually formed of felt or other absorbent material,

soon becomes inefiective in the'perforniance of its function. V Because of the troubles referred to, as Well as others not herein specifically 1IlG11lll01'l(l.

incident to the filling of the oil reservoir above its normal height, it has been the object oi the present invention to provide means for limiting the height of the oil in the reservoir to that assuring the best operation of the boX'. To this end, the invention, in its.

preferred form, comprises theprovision of an overflow opening in the wall of the reservoirpositioned to establish the desired height of the oil therein, a filling opening at a level above the overflow opening and closures for said openings, the closure for the overflow opening being so connected with the closure torth e filling opening as to necessitate its removal either simultaneously with or prior to the removal of thefilling opening closure. 'In this way filling of the reservoir above its norrnal height as established by the overflow opening will be prevented.

Fig. 2is avertical longitt'idinal section of the hon, on the line 2 -21 of Figl, shown in association with the journal end of an axle having an oil clistributor applied thereto.

Fig. 3 is a side view of the front end of the box.

Fig. 4 is a partial front end View of the box showing the overflow opening arranged at one side thereof.

Fig. 5 is an enlarged sectional detail showing the connection between the closures ot' the filling and overflow openings.

Thebox here shown, aside frointhe features" of the presentinvention, is substantially the sa ine as that disclosed in the Eveno Patent No. 1,617,205, to which reference may be had, It coinprises the be): proper, indioated at 1. which is provided at its bottoni with an oil, Well or reservoir 4; ltlountecl in a suitable seat in the top portion of the box is a bearing 3 having an extension 3 overhanging the end or the axle, which latter is provided with the usual journal 5" engaging the bearing 3. Secured to the end of the axle for rotation therewith is the oil elevating device or paddle 2 havin terminal sections 9, which during rotation of the axle, pass through the oil in the up a film or coating of oil which, when the ends of the paddle pass throii'gh the ulaper arc of their rotation, is discharged therefrom for distribution onto the bearing, which hitis provided with the usual oil distributing ducts and channels for leading the lubricant to the engaging faces ot the jbureal and bean ing. The box, atits inner end, is provided with the usual dust guard 6 contact with the axle for preventing entrance of dust or reservoir and pick tnsr onenrs, ISLE ADAM, finance; Assreiion To Isorrriinhand to )our in an excess quantity of oil and thereby bring it up above the normal level adapted for the best functioning of the parts, as hereinbefore referred to. To avoid this 1 provide the box with an overflow opening 11 positioned to establish the desired height of the oil, as indicated at 12, which opening is normally closed by a suitable closure, here shown in the form of a screw plug 13 having a head 14 and an intermediate spacing portion 15 of slightly greater diameter than the plug providing a shoulder 16 for engagement with a washer 17 serving as a seal to more effectively close the overflow against leakage of the oil.

If this closure for the overflow opening is removed each time oil is supplied to the reservoir through the filling opening, it would effectively serve its purpose of limiting the oil to its proper height, but it has been found in practice that it is not so removed; therefore, in accordance with the present invention, I have connected this closure 13 with the filling opening closure 14 in such maner as to render it necessary to remove the closure 13 preliminary to the removal of the closure 14. In this way positively insuring against the filling of the reservoir above the proper predetermined level. Such connection of the closures may be effected in any suitable or desired way. In the present case, the closure 14 is formed with an annular extension 18 overlying the upper surface of the wallcontaining the overflow opening and having an opening or perforation 19 through which the closure 13 extends with its head 14 overlying said extension as shown. With such connection of the parts, it will be clear that the closure 14 cannot be removed without first removing the closure 13.

It will be noted that extension 18 of the closure 14 is spaced from both the underlying wall of the box and from the head 14 of the closure 13 and also that the perforation 19 of the extension is of substantially greater diameter than the part 15 of said closure 13; this spacing of the closures enabling each to be adjusted to their respective seats independently of each other. It will also be noted that the connection of the overflow closure 13 with the closure 14 is such as to permit it to be removed from and replaced in the overflow opening independently of the filling opening closure 14.

To prevent the introduction of oil or other lubricant into the box by only partially opening the cover 14 and permitting the plug 13 to remainin place. means are preferably provided for preventing any such partial opening of the cover 14 without the prior complete removal of the plug. Any suitable means -may be provided for such purpose, the means here sh 0wn comprising a. lug 22 on the box which is arranged to overhang-the front side of the cover adjacent its upper edge whereby .member for the overflow it will be necessary to swing the lower edge of the cover outwardly from the box to release it from said lug and to do which it ohviously will be necessary to first completely remove the plug 13.

As shown in Figs. 1 to 4, the overflow opening is arranged at the front end of the box. This however is only exemplary, such opening may be at one side of the box, as shown in Fig. 5, or any other desired location or arrangement of either or both of the openings may be had without departure from the invention.

While the opening 11 has been herein referred to as the overflow opening, it will of course be understood that it may be also used as a filling opening and, as a matter of fact, is ordinarily so used.

Y'Vhat I claim is:

1. A journal box having an access and filling opening and a reservoir below the same, and also having an overflow opening positioned below said access opening to establish a desired heighth of oil in the reservoir, .1 cover for the access opening, and a closure opening, said closure member also constituting means for pre venting the removal of the cover prior to the removal of the closure member.

3. A journal box having a combined aceess andoil filling opening, and also having a reservoir and. an overflow opening, a cover for the access and filling opening having a portion arranged adjacent the overflow opening, a closure member for the overflow opening and means on the outside of the box ad jacent the combined access and filling opening whereby the cover must be seated prior to the fitting of the closure member in the overflow opening.
